s2, adding a wetting agent, cationic wet strength resin and a dispersing agent into the mixed raw material prepared in the step S1, and uniformly stirring to prepare a mixed dispersing material;
and S3, adding the temperature control microcapsule and the water-based cellulose acetate into the mixed dispersion material prepared in the step S2, and uniformly stirring to obtain a semi-finished product of the ink.
And S4, adding the pigment, the defoaming agent, the flatting powder and the polyethylene wax which are required to be printed in the semi-finished product of the ink prepared in the step S3 according to the requirement, and uniformly stirring to prepare the self-drying water-based ink with strong adhesion.
Compared with the prior art, the invention has the following advantages:
1. the adhesion and flexibility of aqueous inks to substrates depend on the properties of the polymer emulsions, which are generally based on acrylic resins and are of a wide variety. While these polymers have poor heat resistance, softer, low glass transition temperature (Tg) polymers generally have better adhesion and flexibility when used on many thin film substrates; the sample using the nano copolymer as the adhesive is improved in water resistance, color density and viscosity; the water-based ink can be used for paper, carving and double-sided printing, and can or carton manufacturing; the viscosity of the nano St/BuAc polymer is slightly higher than that of a conventional polyether siloxane copolymer, and this higher viscosity reduces the spreading of the ink on the surface, which increases the stain resistance and makes it less prone to flaking. The cationic wet strength resin is added, the high-density positive charges on the polyamide epichlorohydrin molecular structure and the negative charges on the fiber structure are mutually acted and remained on the fiber surface, the active groups on the molecules and the hydroxyl groups on the fiber are subjected to chemical reaction to form a stable chemical bond structure, and the water molecules can be prevented from damaging the fiber, so that the water resistance of the product can be enhanced by using 'bridging' of molecular chains; after a proper amount of flexographic ink was applied to the paper by a hand-operated roller, the paper was immersed in distilled water at 25 ℃ and allowed to stand for 30 seconds. It is then observed whether ink has run off the paper. As shown in FIG. 1, the nano St/BuAc polymer has strong hydrophobicity, and can greatly improve the water resistance of the printing paper.
2. After the temperature control microcapsule is mixed with waterborne polyurethane, waterborne cross-linking agent, waterborne self-crosslinking acrylic acid and waterborne cellulose acetate, part of cross-linking polymer is adhered to the surface of the temperature control microcapsule through hydrogen bonds or Van der Waals force to form certain steric hindrance so as to prevent calcium oxide in the temperature control microcapsule; when the oven of the gravure press is heated to raise the temperature, the cross-linked polymer and the shell material on the surface of the temperature-controlled microcapsule are broken, and the released calcium oxide reacts with water in the water-based ink to release heat, so that the water-based ink is quickly dried.

in this example, the desiccant is calcium oxide powder.
The second purpose of the invention is to provide a preparation method of degradable self-drying water-based ink, which comprises the following steps:
s1, uniformly mixing waterborne polyurethane, waterborne self-crosslinking acrylic acid, a waterborne crosslinking agent, st/BuAc copolymer and deionized water according to a ratio to obtain a mixed raw material;
s2, adding a wetting agent, cationic wet strength resin and a dispersing agent into the mixed raw material prepared in the step S1, and uniformly stirring to prepare a mixed dispersing material;
and S3, adding the temperature control microcapsule and the water-based cellulose acetate into the mixed dispersion material prepared in the step S2, and uniformly stirring to obtain a semi-finished product of the ink.

The degradable self-drying water-based ink prepared in the examples 1 to 5 is subjected to a performance test, and specifically comprises the following contents:
1. ink adhesion test
The adhesion was tested according to the standard test method ASTM D3359A, and the ink binding fastness performance effect was classified into 4 grades: preferably 5, good 4, medium 3, and poor 2. Testing the binding fastness performance of the neutral paper substrate:
TABLE 1
| Examples | Grade of bond fastness Properties |
| 1 | 5 |
| 2 | 2 |
| 3 | 3 |
| 4 | 4 |
| 5 | 2 |
As can be seen from FIG. 1, the binding fastness performance of the water-based ink prepared by the invention is remarkably improved compared with that of the common water-based ink, but the binding fastness performance is reduced with the increase of the drying agent, and the optimal mixture ratio is example 1.
2. Microcapsule coating effect test
To test the coating effect of the microcapsules, the same mass of calcium oxide and the microcapsule desiccant of example 1 were added to water, and the pH changes of the water containing different additives at 30 ℃,40 ℃,50 ℃,60 ℃,65 ℃,70 ℃ and 80 ℃ were measured while the other conditions were kept constant, and the results are shown in fig. 2.
As can be seen from FIG. 2, the calcium oxide powder undergoes a vigorous hydrolysis reaction upon contact with water, the pH value of the solution gradually increases due to the increasing concentration of [ OH- ], and the pH value of the solution reaches 9.21 at a temperature of 30 ℃. The calcium oxide powder treated by the microcapsule process has good chemical stability at the temperature of 20-60 ℃, and the pH value is basically kept unchanged. With the further increase of the temperature, the shell material is continuously impacted under the action of Brown motion of water molecules, the shell material falls off from the surface of calcium oxide, calcium oxide powder is in contact with the water molecules to generate chemical reaction, and the pH value is rapidly increased.
Therefore, the microcapsule drying agent is coated well, the water resistance of the tested microcapsule is good, and the rupture condition of the microcapsule drying agent at 60-80 ℃ (the common heating temperature of a gravure press oven) completely meets the use requirement.
3. Drying Effect test
To test the effect of the drying agent on the drying properties of the aqueous gravure inks, printing was carried out on neutral paper or tipping paper using the inks of examples 1 to 4, the oven temperature being set at 80 ℃ and the drying effects of the inks at speeds of 30, 40, 50, 60, 70, 80, 90, 110, 120m/min were recorded, respectively. The ink drying effect was divided into 4 grades: preferably 5, good 4, medium 3, and poor 2. The drying effect comparisons of the inks of examples 1-5 are shown in the following table.
Therefore, under the condition that the drying effect is also 5-grade excellent, the printing speed of the ink added with the microcapsule drying agent can be improved to more than 120m/min from the original 30m/min, and the production efficiency is greatly improved.
The inks of examples 1 to 4 were likewise tested for drying effect: the temperature control microcapsule type drying agents of the embodiments 1 to 4 can effectively improve the drying speed of the water-based plastic gravure ink, the drying speed of the water-based ink containing the microcapsule drying agents is obviously increased, the speed can be improved to more than 120m/min from the original 40m/min, and meanwhile, the printing adaptability of the ink is good, and the printing quality of a printed matter is good. The embodiment of directly adding the desiccant powder has poor printing adaptability due to the premature effect of the desiccant, and cannot be used at 70 m/min.
The invention can be widely used for paper, engraving and double-sided printing, and can be used for manufacturing cans, cartons, paper printing and tipping paper printing, solves the bottlenecks of poor adhesion fastness, low color density and low drying speed of water-based gravure ink, has good ink leveling property and excellent printing effect, and has good water resistance after the ink is dried into a film.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
